Abstract

In the present investigation, a series of sliding and tensile tests were conducted to simulate interactions at the bearing surface. A spherical tipped aluminum pin was slid against a polished steel ring. Results showed that the friction coefficient at all test temperatures of sliding exhibited a near similar pattern of peak followed by a gradual drop and stabilization. The steady state friction coefficient was 0.2 for temperatures up to 423 K, and greater than 1.0 for temperatures above 423 K. The transfer layer evolution was dependent on friction force. The ultimate tensile strength decreased at temperatures higher than 423 K.
